Problem description
For phetsims/qa#519
Very minor. Feel free to close if it doesn't need to be addressed. On the second screen, if you have the Sun/Planet/Moon scene active and you have ?showPointerAreas on you will see that the area for the Moon is larger than the area for the Earth. This difference seems odd to me. May have come out of other Pointer Area changes.

This was fine tuned in #338, @arouinfar can you please advise?

[arouinfar]

@samreid I think it's fine as-is. We fine-tuned the touch areas in #338, which optimized things for the Model screen where the bodies are visible. On the To Scale screen, the objects are so small that users are likely grabbing the label.
